It's more sensitive than PIR sensors and works well for occupancy detection, automated lighting, and security systems. The module outputs a voltage signal upon detecting motion, making it easy to interface with microcontrollers.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating frequency\u003c\/td\u003e\n\u003ctd\u003e5.8 GHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection range\u003c\/td\u003e\n\u003ctd\u003eUp to 7 meters (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput voltage\u003c\/td\u003e\n\u003ctd\u003e4–28 VDC (typically 5V)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput signal\u003c\/td\u003e\n\u003ctd\u003e3.3V TTL logic level (high on motion)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePenetration\u003c\/td\u003e\n\u003ctd\u003eNon-metallic materials (wood, plastic, glass)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e28.5mm × 17.8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eTouchless light switch that activates when you enter a room\u003c\/li\u003e\n  \u003cli\u003eOccupancy-based energy‑saving systems for home or office\u003c\/li\u003e\n  \u003cli\u003eHidden security sensor to detect intruders through walls\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/esp32-garage-door-opener-kit-auto-open-and-close-via-phone-ble\"\u003eAutomatic door opener or garage presence detector\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eWorks with any microcontroller that can read a digital input, including Arduino, ESP8266, ESP32, Raspberry Pi (with level shifting for 5V logic). The module has a 3.3V regulator, so it can be powered directly from 5V or a battery within the wide input range. Pair it with a relay module for controlling mains appliances.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VIN to 5V (or up to 28V), GND to ground, and OUT to a digital input pin. The output goes HIGH for a few seconds when motion is detected; keep the antenna area clear of metal for best range. Add a 10kΩ pull‑down resistor if using with a sensitive MCU input.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
